Question

Plssss help i need a good grade

Answer 1

D.

Explanation:

• so first we'll write the exponential form which is: 3²ˣ⁻¹⁶=3⁴ˣ⁻¹²
• since we got the same bases the exponents can now be written as equals: 2x-16=4x-12
• Switch the numbers around to get the x's on one side and the numbers on the other side: 2x-4x=-12+16
• Add/subtract the values: -2x=4
• divide by -2 to get x by itself: -
  `(-2x)/(-2)` =
  `(4)/(-2)`
• that should leave you with option D: x=-2

Answer 2

Its either 2 or -2

Explanation:

Im sorry, im not entirely sure which one but im pretty sure its a negative (i get confused sometimes)

Just go with one of those two answers ( C or D)
